Benefits of technology
[0006]It is an object of the invention to provide a connector in which, while miniaturization and thinning are attained at a level equivalent to the conventional art, it is possible to prevent a phenomenon that molten solder drips from a wire connecting portion to form a solder bridge between adjacent contacts, from occurring, and a lead wire can be soldered to the wire connecting portion with excellent workability and high strength.
[0028]As described above, according to the invention, it is possible to provide a connector in which, while miniaturization and thinning are attained at a level equivalent to the conventional art, it is possible to prevent a phenomenon that molten solder drips from a wire connecting portion to form a solder bridge between adjacent contacts, from occurring, and a lead wire can be soldered to the wire connecting portion with excellent workability and high strength.
Problems solved by technology
In the conventional art, a lead wire is soldered to the wire connecting portion which is inclined by about 45 deg., and hence there is a problem in that molten solder easily drips from the wire connecting portion to form a solder bridge between adjacent contacts.

Embodiment Construction
[0044]Hereinafter, an embodiment of the invention will be described in detail with reference to the drawings.
[0045]In the following description, unless otherwise specified, it is assumed that the direction of the arrows a-b in FIG. 3 is the anteroposterior direction (the longitudinal direction of a connector) which is the insertion / extraction direction of the connector with respect to a counter connector, that of the arrows c-d is the lateral direction (the width direction of the connector) which is a pitch direction perpendicular to the insertion / extraction direction, and that of the arrows e-f is the vertical direction (the thickness direction of the connector) which is a direction perpendicular to the insertion / extraction direction and the pitch direction.
[0046]In FIGS. 1A, 1B, 1C, 2A, and 2B, the reference numeral 1 denotes an A-type micro USB plug (for a cable harness) which cooperates with an AB-type receptacle (counter connector) that is disposed in a portable telephone, a di...

The invention provides a connector in which, while miniaturization and thinning are attained at a level equivalent to the conventional art, it is possible to prevent a phenomenon that molten solder drips from a wire connecting portion to form a solder bridge between adjacent contacts, from occurring, and a cable can be soldered to the wire connecting portion with excellent workability and high strength. In the connector of the invention, each of terminal portions (25) of plural contacts (20) which are juxtaposed in the pitch direction has a wire connecting portion (26, 27, 28) to which a lead wire (71, 72, 73, 74) drawn out from a cable (70) is to be soldered. The wire connecting portion is expansively opened along the connector thickness direction which is perpendicular to: an insertion / extraction direction of the connector with respect to a counter connector; and the pitch direction perpendicular to the insertion / extraction direction.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a connector.[0003]2. Description of the Prior Art[0004]A technique relating to a connector has been proposed which comprises: plural contacts that are juxtaposed in the pitch direction; and an insulative body that holds the contacts, and in which a wire connecting portion is formed in the rear of the contacts in order to solder a lead wire drawn out from a cable. In the proposed technique, the bending angle of the wire connecting portion, which is conventionally bent at a right angle, is suppressed to about 45 deg., whereby the connector is miniaturized and thinned (for example, see Japanese Patent Application Laying-Open No. 2004-158288).SUMMARY OF THE INVENTION[0005]In the conventional art, a lead wire is soldered to the wire connecting portion which is inclined by about 45 deg., and hence there is a problem in that molten solder easily drips from the wire connecting portion to form a ...
